There may be any number of references associated with a given update of a locality or species. References, once entered, can be re-used in association with additional species or localities. The Database software allows the operator to locate and re-use reference records in this way.
The data fields for references are described below. Fields for species
references and locality references are identical, and, in fact, the same
reference entity in the Database can be associated with either species
or localities, or both.
The source of a literature reference.
DATA TYPE
A character field not to exceed 300 characters.
DESCRIPTION
The full citation of the reference, in Paleobiology format (except for italicization). Thus, for journals: J. Omnology 124: 1-54. For Books: Vanishing Press; Chicago, Illinois. For edited volumes: Pp. 192-215. In: T. J. M. Schopf, ed. Models in Paleobiology. Freeman, Cooper & Co.; San Francisco.
INTERNAL TABLE.FIELD NAMES
ref.citation
ALLOWED VALUES
Any
The year of publication of a reference.
DATA TYPE
A character string not exceeding 4 characters. MANDATORY FIELD.
DESCRIPTION
Year of publication of a reference -- or, the date information was obtained, if this is not a published reference. Internally, all references are assigned unique ID numbers by the computer, and kept track of using the ID. However, most of the time researchers will want to search on or specify references by first author's last name (at least) and by date (this is why these fields are mandatory). Multiple references by the same first author in the same year are still distinguished internally by their ID numbers; searching by author and date alone will pull up a list of all references matching the query.

A character field not exceeding 20 characters. MANDATORY FIELD.
